Myself and a friend saw a spherical (football shaped) object hovering approximately 100 feet up and approximately 500 feet away in a northwesterly direction. The object appeared without sound, jumped to two different locations and then disappeared.

The object was approximately the size of two 747's one on top of the other and had muted lights going around the center of it, in this sequence red, yellow, green,blue.The object made no sound and hovered for about 10 seconds, jumped to another location for about 2 seconds, then again for the same duration and then disappeared. It was an overcast evening, the ground was covered with snow and it was in a very well lit park at the edge of Carlton University campus. The park was deserted but there were cars driving directly under the object. The conclusion that my friend and I made was that it was undeniably extraterrestrial and could not possibly be an experimental craft or any other form of illusion ie: balloon.  When the object jumped from one location to another it was an approximate leap of 500 feet.
